Pocahontas No. 3 Coal Bed Point Data (Chemistry) in Virginia and West Virginia

This dataset (located by latitude and longitude) is a subset of the
geochemical dataset found in Chap. H, Appendix 2, Disc 1, and used
in this study of the Pocahontas No. 3 coal bed. That dataset is a
compilation of data from the U.S. Geological Survey's (USGS) National
Coal Resources Data System (NCRDS) USCHEM (U.S. geoCHEMical), The
Pennsylvania State University (PSU), and the West Virginia Economic and
Geological Survey (WVGES) coal quality databases. The metadata file for
the complete dataset is found in Chap. H, Appendix 3, Disc 1
(please see it for more detailed information on this geochemical
dataset). This subset of the geochemical data for the Pocahontas No.
3 coal bed includes ash yield, sulfur content, SO2 value, gross
calorific value, arsenic content and mercury content for these
records, as well as the ranking of these values, which is described
later under the attributes in this metadata file. Analytical techniques
are described in the references in Chap. H, Appendix 4, Disc 1. The
analytical data are stored as text fields because many of the parameters
contain letter qualifiers appearing after the numerical data values. The
following is a list of the possible qualifier values: L - less than, G -
greater than, N - not detected, or H - interference that cannot be
easily resolved. Not all of these codes may be in this database.
